3 Be it known that I, DANIEL HUG, a citizen of' theUnited States, residing at Denver, in the county of 'Arapahoe, State of Colorado,

ave invented a new and useful Improvement in Breech-Loading Firearms, which improve mentis-fully set forth in the following specification and accompanying drawings.-

My invention relatesto breech-loading lire arms of the general construction disclosed in a former patent granted to me;- and it consists more especially in improvements in various .details therein whereby the constructionis simplified and rendered more effective throughout. v

The invention consists, first, in an improved construction'ot'pin-bolt, which is provided 'with a spring fastened there in a novel manner, the head of said spring overlapping a recess in the end of said -bolt, whereby it will be impossible for any minute particles,.such as grains of sand or similar material, to become interposed between the spring and bolt, so as to renderineli'ective the operation thereof,'said head having an upward extension to prevent unlocking.

Thcinvention also consists in an improved construction of breech-block, which is provided with an overhanging projection to form a housing within, which is located a spring which is adapted to bear'upon asuitable portion of the, extractor employed.

It also consists in an improved construction of recoil-b1ock,'which is adapted to be pivotally mounted upon and work in unison with the breech-block, said recoil-block havinga channel and inclinedwalls and recesses therein adapted to coach with a contiguous scribed, and particularly pointed outin provided for p re've'u t i u g ri-n g of the gun when not desired. I

It also consists of an improved'manner of .siip'portingthe maiuspring and its adjuncts.

It further consistsof noveldetailsof construction, alias willbe hereinafter fully de- .the

claims.

Fig. 7 rep'resents'a perspective view-of the hammer in detached position. v Fig. 8'reprepost to the recoil-block and the right-hand wall of the frame and showing also means for actuating said post. Fig. 13 represents a section'on the line .2 2, Fig. 11'. Fig.14t rep' resents a section on'line m, Fig. 2, showing the relative position of the extractor, harnmer, and breeclrblock when assembled.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, ldesignates a breech-loading firearm, the sa'mehaving the trigger-plate 2, upon which is supported the inainspring 3, the latter being secured there- -loo - is teated in the fore-stock 7.

, The free end 8 of the mainspring 3 isprovided with a roller 9, which is adapted to contact with a face of the heel 10 of the hammer 11, the latter having the firing-pin 12 formed, preferably, integral therewith, said firing-pin being adapted to work inand protrude through the opening 13 in the breechblock 14, the latter haying at its upper rear portion a plurality of cars 15, which fit, respectively, in recesses 16, formed on opposite sides of the forward portion of the recoilblock 17. 18 designates a pin--bolt which .passes through openings in the ears of said breech-block and recoil-block, theconstruction of said pin-bolt being best u derstood from Fig. 9, in which 19 designates he body of the bolt, the same having the head 20 and the longitudinally-extending recess 21, said recess terminating with the trahsverseopening 22, in which latter is seated the extremity 24 of the spring 23, which latter terminates in a head 25, which is adapted to be seated in the recess 22?, it being noted that said head 25 has a lower overlapping portion 27, which covers any space which might exist between the recess 22 and thelongitudinallyextending groove 21, the upper portion 26 of said head 25 being rounded or chamfered, so as to permit the bolt to be readily inserted in position, said portion 26 also preventing disengagement of said pin, it being noted that the outer portion of the car 15 of the recoilblock 14 has an annular groove or recess 18 therein, in which the end of said pin 18 and its head 25 terminates.

28 designates a spring which is interposed hetween the breech-block and the recoil-block at a point below the horizontal line of the ears common thereto.

1 nier, so that the latter engages with the end 39 of the sear 40, whereby it is cocked, said sear having the spring 40 34 designates an extractor, the same hav ing an offset upper portion 35, the general location of which in the frame 41 andiits function will be understood from Fig. 14.

The lower portion of the extractor has the rearward extension 36 and the curved wall 37, which contacts with an end of the spring 42, which. is secured in position within the housing formed byan overhanging projection 43 of thebreech-block 14.- by means of a pin 44 or other suitable fastening device.

The extractor, hammer, and breech-block are assembled in the frame 41 in the order indicated in Figs. 8 and 14, the same being all mounted upon the sleeve 45, through which passes the pin-.boltafi, the construction of the latter being substantially identical to that of the bolt seen in Fig. 9, although it will of course be apparent that saidpins are of different lengths and that the extremity of the pin 46'i s seated in the recess of the outer wall of the frame. ,The unlocking or disengagementof the pin-bolts 18 and 45 is prevented by reason of the engagement of the deflected portion 26 of the head 25 and of a corresponding spring in the journal-pin 4.6

with the contiguous portion of the 1 part in which said pin isinserted, as is evident.

The construction and function of the safetypost will now be described, reference being had more especially to Figs. 2, 11, 12, and 13. Figs. 11, 12, and 13 are views of the portion of the right-hand wall of the frame carrying the safety-post, while in Fig. 2 the right-hand wall of the frame is removed, but the safetypost is shown in the position it occupies, the position of the finger-piece for operating the safety-post and the slot in said wall within which it moves being shown in dotted lines, it being understood that the longitudinal section through the frame is taken on a line ex tending along the inner face of said righthand wall thereof. The right-hand side 47 of the frame il has a recess 48 therein that extends from a point near the upper edge thereof downwardly. The safety-post 49 is situated therein, and the sear 40 extends across the lower end thereof, whereby the lower end of the safety-post can be moved into the path of the sear. The safety-post 49 is fulcrumed at the .point 50 and has attached thereto the pin 51, which latter projects through a slot 5]? in the side of said frame, said pin being provided with the finger-piece 52, which is seated in a recess 53 in the outside Wall of the frame 41. The position which the safety-post normally occupies is indicated in full lines in Fig. '12, it being seen that said post when seated in its recess is normally out of the path of the recoil-block 17. The top extremity 54 of the safety-post is normally in contact with a curved wall 55 in the upper portion of the recess 48, as will be understood from Figs. 12 and 13, whereby it will be seen that when the pin 51 is actuated in the proper direction, in the present instance backwardly, or in the direction indicated by the arrow (0 in Fig. 2, the top 540E the safety-post will be deflected and moved under and into contact with the portion 56 of the rceoil-block17. As a result of the above movement the lower portion 57 of the safety-post will now be in contactwith the portion 58 of the scar, which latter, it will be understood, is sealed in the lower end portion of the recess 48, in which the post 49 is placed, whereupon it will he apparent that the scar cannot be moved upwardly by the trigger i), and consequently the gun cannot be fired and the action cannot be opened, and the cartridgeis thus prevented from falling out.

The operation isas follows: The parts after firing appear as seen in Fig. 2, and when it is desired to cock the. gun the thumh-piece'o'f' the recoil-block 17 is rocked until the latter assumes the position seen dotted in Fig. 2, whereupon it will be evident thatthe recess 32 will engage the part 11 of the hammer ll and the recoil-block, breech-block, hammer, oxtractor, and their adjuncts can now he rocked into the position seen in Fig. l. The operator can now insert a cartridge in position, and simultaneously with the insertion of the cartridge the pal m of the same hand comes in contact with the thu m'o-piece of the recoil-block and the latter and the brcech-blockare moved upwardly into the position seen in Fig. The pulling of the trigger disengages the sear from the hammer and the tiring-pin strikes the cartridge, the parts now appearing again as seen in Fig. 2, as is evident. The function of the safety-post if) is to engage the sear when'liesircd, and so prevent thopossihility of the latter moving up and disengaging the hammer, while at the same time the top-of said safety-post is moved "he position seen in Fig-11 and in dotted nncs in Figs. 12 and 13, wherefroin it will he soon that the breech cannot be opened, and, if'desired, the

gun can be suspended in a vertical position upon a ,iingeror-fingers by means of the trigger 30 without firing. it will also be noted that the lower end of the extractor-spring having come into contact with the lower end of the extractor on opening the breech thereby starts the shell by leverage,:'the action of the spring throwing the shell'rout. it will thus be seen from the foregoing that by the provision of the safety-post constructed as described, the breech-block provided with the Spring and the housing therefor, the recoil-block provided with the recess 32, the

function of which has been already explained,

and'the' pin-bolts'having the headed springs constructed as described I have produced superior and exceedingly-ancient firearm in which but three movements are necessary first, a single backward movement of the hand to bring the parts from the position seen. in Fig. 2 to the position seen in Fig. 1; next comes the act of inserting the cartridge and bringing the recoil-block into the position seen in Fig. 3, and, third and lastly, pnliing the trigger 59, hywhich the firing is accomplished. i

' t will be evident that slight changes may he made by those skilled in the art which will come within the eco e of m invention and I do not, therefore, desire to be limited to the" exact construction I have heroin shown and described.-

Patent, is
